Chemical Structure
Description
1,3,5-Benzene-2,4,6-d3-tricarboxylic Acid (CAS 62790-27-6), molecular formula C9H3D3O6 and molecular weight 213.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3,5-Benzene-2,4,6-d3-tricarboxylic Acid (C9H3D3O6) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 213.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
